Upwelling, driven by equatorward-blowing winds, is a physical process of lifting cold, nutrient- rich water from deep in the ocean to the surface. Upwelling fuels the high seasonal primary production at the base of the CCE food web. The timing, strength, and duration of upwelling vary greatly along the coast.

Data sources CUTI and BEUTI are updated with data from the near-real-time (NRT; https://oceanmodeling.ucsc.edu/ccsnrt/) data-assimilative models.
Bakun UI is derived from geostrophic estimates fro winds derived from FNMOC sealevel pressure estimates.
Additional Information new estimates of coastal upwelling, specifically the vertical water volume transport (Coastal Upwelling Transport Index; CUTI) and the vertical nitrate flux (Biologically Effective Upwelling Transport Index; BEUTI). We now use these indices to describe upwelling in the CCE reports, as they better represent surface winds, ocean circulation, and subsurface variability. CUTI provides more accurate estimates of vertical transport of water. BEUTI provides additional information about the nature of the upwelled water (e.g., its nitrate content) that can be linked to ecological processes such as productivity Jacox et al. (2018).
Daily values of CUTI and BEUTI are derived from numerical model outputs described in Jacox et al. (2018). Detailed information about these indices can be found at https://mjacox.com/upwelling-indices/.
